Industry observation: the current international situation of digital printing

since the 1990s, inkjet printing technology has been widely used in textiles, and chemical, print head, printing machine, fabric and software manufacturers have begun to try to cooperate with each other. The cooperation of various industries makes the printing quality of textiles exceed the traditional printing standards. However, the emergence of a new era of cooperation has both advantages and disadvantages for users. Most of the advantages are that the cooperation of various industries leads to the emergence of appropriate machines, components, chemicals and software, which ensure the safety of the program. The emergence of first-class Epson print heads has set a milestone for textile inkjet printers, and almost all related inks can be applied to these print heads. One of the disadvantages is the lack of compatibility between competitive systems. For example, there is a compatibility problem between the systems of BASF in Germany and stork in the Netherlands, Huntsman and REGGIANI

new progress in ink research

ink includes solvent ink and weak solvent ink. In addition to the familiar CMYK, which is used for heat transfer printing, there are also some special colors, such as dark blue, dark red and orange. At present, many manufacturers, such as Trident company in Brookfield, USA, have produced 12 colors of ink

the printer made by Epson is equipped with a piezoelectric sensor nozzle, which can accurately spray color drops on the fabric. It is skilled. The variable print head can use different inks, such as solvent ink, sublimation ink, active ink and pigment ink

many inkjet printer suppliers also provide corresponding software (which can be produced by themselves or in cooperation). Using these software, some image data can be modified into commands and controlled by computer. Although the print heads may be different from different manufacturers or different batches of the same manufacturer, RIP software, as the heart of the inkjet printing system, must be customized for each print head

The basic task of RIP software is to receive scanned digital images, color separation and color management, and the inkjet system is controlled by digital technology

now, different designs of dryers can dry solvent inks, including infrared dryers and ultraviolet dryers, which are installed on the printing machine in order and match the printing speed. The printing speed is generally m2hr, and some can reach 150m2hr or more, such as hpscitex ts8300 and Italy REGGIANI dream digital jet printing machine

but in general, the most important thing is the printing quality. It is understood that the better the printing quality, the slower the speed

pigment inks: now there are many manufacturers for sale, including BASF, Huntsman, DuPont, Wilmington, and some small manufacturers. Due to the late development of pigment ink and its great technical difficulty, the particle size of pigment is particularly sensitive to the blockage of nozzle and the rheology and stability of ink during ink-jet printing. At present, the average number of printed fabrics produced by pigment printing process in the world is 40% - 50%. The pigment must be crushed into tiny particles and dispersed in the aqueous solution to form ink, which can be regarded as water-soluble ink. Such ink does not need to be pretreated, as long as it is dried after printing. It is said that UV drying agent will play a greater advantage in pigment ink, usually installed directly on the printing press

UV resistant ink: mainly used on outdoor flags and banners, DuPont introduced a special artistri solarbrite ink, which is said to have extraordinary light fastness

ink for luminous printing of dark fabrics: white or luminous printing of some dark fabrics is mainly used for advertising T-shirts

at present, American reenprint inkjettechnology company can produce inks that can meet this requirement, such as their fastink2, which are pigment inks. During printing, as in screen printing and transfer printing, pretreatment procedure is necessary. It can form a closed system on the surface of the fabric, which can prevent white printing pigment from penetrating into the fabric. In addition, ralfbenz, an expert who has used fastink technology, said that in this pretreatment process, paint spray guns must be used, especially when dealing with dark T-shirts. Ralfbenz is the head of schilder+druckwerbetechnik in geslingen, Germany, and is also a user of fastink technology. The manufacturer said that although its fastness is not as good as that of plasticized sol printing, it is enough to achieve the above purpose, and its washing fastness is also very good

complete solution of pigment ink

at present, there are not many pigment inks used for ink-jet printing of textiles, and the inks used are mainly dye inks. As the two giants in the printing and dyeing industry, BASF and stork are cooperating to develop an easy-to-use, high-performance pigment ink for textile digital printing. Stork is the largest company with printing solutions in the textile industry and the advertising shirt industry. This new type of pigment ink has been officially introduced to the market at the turkey International Textile Machinery Exhibition held in Istanbul in June this year. Not only BASF's high-tech knowledge of ink makes the color of pigment ink colorful, but also makes the printing speed more suitable, but also stork's research on printing process and ink feeding system make these properties more possible. This pigment ink has passed the storkusee certification, and storkusee has been recognized as a very authoritative standard in terms of printing quality. Storkusee's qualification certification enables people to get the same printing quality at any place and at any time. For example, printing can be carried out in Asian manufacturing centers, and products can be produced locally

DPA is the first textile digital printing factory in the world to produce standard digital textiles, and printunlimited company in the Netherlands is a printing company that has just qualified to produce this product. Now the network of this sample service system is planning to expand to major design centers around the world

constantly developing digital printing machines

Company n, located in Seoul, South Korea, is a company that produces a series of digital printing machines. The teleios series digital printing machines of the company's model txv874 have a printing width of 187 cm. Now, this kind of printing machines have new features to improve their production efficiency. At present, V8 printing machine has 8 print heads instead of 6, which makes it easier to change colors when printing. Teleiosv8 digital jet printer adopts a 24 color scheme and is equipped with a suitable dye reservoir to store about 1 liter of dyes of different colors respectively. It is reported that such a device does not need to manually add dyes or replace the dye reservoir in the production process, and the seasoning time and temperature should be suitable for the inkjet and printing speed

printing and seasoning can be carried out synchronously from the beginning to the end of the work. An effective external extraction system is directly connected to the printing machine, which can be extracted for seasoning within a period of time, so as to prevent the dye steam from evaporating. This system also improves the production efficiency and is expected to make the printing speed reach 50m2hr. The teleiostx100 digital printing machine of N company still has six print heads. You can call our order hotline for the width: 0531 (8) 7566760, which can reach 260 cm. You can use 16 color or 44 color schemes

hpscitex now recommends a trucolor digital inkjet printer from 3pinkjettextiles, Germany. When using solvent ink (tj8300) and UV ink (tj8500), 3ptrucolor can ensure its printing quality, and the 3P paper lamination structure ensures the best media transfer in the printing process. The special trucolor coating finish prevents the influence of ultraviolet light, humidity and wear on the fabric

seidenwebereig sken, located in Krefeld, Germany, is an authoritative company producing jacquard woven fabrics. At present, it has launched a new brand artido, According to the person in charge of the company, the launch of the new brand is to explore a broader market. Artido will use its unique printing technology to establish a new set of quality standards. People can get products that satisfy themselves without leaving home, as long as you transmit your data to artido! Station, indicate your requirements, and enter your detailed address, G sken company will carefully transmit the data to the version through the digital program

at present, the virtu7200 print head of Leggett plattdigitaltechnologies in the United States is equipped with a new automatic loading system, which will simplify the fabric cross cutting procedure. In addition, the print head is also equipped with directuv, which can print directly on the fabric without the usual transfer printing paper. The company also supplies finished virtuprint fabrics

in textiles for advertising, digital printing technology has become a relatively mature technology, while in textiles, digital printing is still limited to samples, disposable work clothes and short processes. In the next few years, the quality of digital printing will be further improved and the cost will be further significantly reduced. On the ordinary roller printing machine, if 300 meters of each color can be printed, it will be a major technological breakthrough in the printing industry. The ball screw function of the electronic universal testing machine. It is gratifying that printing machines that can achieve this goal already exist, such as the REGGIANI printing machine of hpscitex company

some small width desktop printers (with a maximum width of 3.3 meters) used in the advertising banner industry sell very well, such as DuPont's artistri3320 printing machine, some of which are used to process household textiles and clothes with a width of CM. DuPont's artistri printing machine has been listed on the company's international station for sale

compared with traditional printing, digital ink-jet printing has the advantages of high flexibility in the production process, good reproducibility, high precision, a marketing system suitable for small batch and fast delivery, meeting the requirements of cleaner production and remote ordering. These advantages make digital ink-jet printing an important research object. Textile digital ink-jet printing has strict requirements not only for ink and computer software development, but also for printers, pre-processing equipment, post-processing equipment, fabric grade and width. When investing in ink-jet printing, enterprises should consider the consumption of ceramic materials, such as ink, chemicals, fabrics, and staff training fees
